Has anyone seen this? I’m a bit concerned as it seems experimental to me.
Based on the search results, some of the influenza vaccines available for the 2024-2025 flu season in the UK do carry a black triangle symbol. Specifically:
The following vaccines are designated as black triangle products for the 2024-2025 flu season in the UK:
1. Adjuvanted quadrivalent inactivated influenza vaccine (aQIV, made by Seqirus)[1]
2. Quadrivalent cell-cultured inactivated influenza vaccine (QIVc made by Seqirus)[1]
3. Quadrivalent Influenza Vaccine – High Dose (QIV-HD, made by Sanofi)[3][5]
The black triangle symbol (▼) indicates that these are newer drugs and vaccines for which the Commission on Human Medicines and the Medicines and Healthcare products Regulatory Agency encourage the reporting of all suspected reactions[1].
It's important to note that not all flu vaccines for the 2024-2025 season carry the black triangle symbol. The presence of this symbol on certain vaccines is part of the ongoing safety monitoring process for newer medical products in the UK.
